Indium Corporation Announces New Cleanable SiPaste® for Microprinting

Indium Corporation^® has added to its portfolio of micro-printing pastes a halogen-free, washable solder paste specially formulated for micro-printing, seen in the 01005 and 008004 components.

Chipaste^® The C201HF combines industry-leading superior No-Wet-Open (NWO) performance with superior stencil print transfer efficiency to meet a wide range of process requirements and improve SPI yields. It leaves a washable residue that can be removed with commercial semi-aqueous cleaning solutions or can be used as a standard no-clean paste in processes where post-reflow cleaning is not applicable.

Chipaste^® The C201HF has excellent transfer efficiency in fine feature apertures with consistent process yields of less than 80 µm.Chipaste^® The C201HF offers:

• Uniform and tight solder deposit across multiple prints.Excellent responsiveness to pauses
• Minimize voids in narrow-pitch parts and ensure joint strength in small parts
• Excellent reflow performance on highly warped parts
• Minimize bridging during the assembly process to improve slump performance and improve yield of narrow pitch parts
• Flexible cleaning; can be used in processes that require or do not require cleaning with saponifiers
